An athlete's coach told him that muscle times speed equals power.
Then according to him the dimensions of muscle are

A quantity $$X$$ is given by $$\epsilon_0 L\dfrac {\Delta V}{\Delta t}$$, where $$\epsilon_0$$ is the permittivity of fee space, $$L$$ is length, $$\Delta V$$ is a potential difference and $$\Delta t$$ is a time interval. The dimensional formula for $$X$$ is the same as that of

The correct statement about Poisson's ratio is:

The dimensions of quantity $$ \dfrac{1}{\mu_0} (\vec{E} \times \vec{B})$$ are:
